PENNSYLVANIA. Ii

Specification of Letters Patent.

Patented Dec. 25, 1906.

Application filed May 15,1905.- Serial No. 260,545.

To all whom it may concern.-

Be it known that we, SAMUEL J. GIBBONEY and JOHN W. RYAN, citizens of the United States, residing at Mount Pleasant, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Multiscopes, of which the following is a specification, reference being had therein to the accompanying drawm s.

but present invention relates to improvements in multiscopes and the main object of ourinvention is the provision of a multiscope by which amazing, amusing, and interest' experiments may be obtained. To this en we provide a peculiar construction of case or casing 0 en at both ends and slightly tapered, and in t e enlarged end we mount a crystal or lens containi I facets, the sma er end being opened and meant for a peep or observation hole. By so constructing this device the object at which the lens is pointed is multiplied and in the special form we employ is increased twentyfour times.

To attain these objects our invention consists of a multiscope embodying novel features of construction and combination of parts substantially as disclosed herein.

In the accompanying drawings, Figure 1 is a pers ective view of the complete device. Fig. 2 1s a sectional view through the lens and the case. Fig. 3 is a sectional view showing the lens inverted. Fig. 4 is a detail view.

Referring to the drawings, A designates a lens or crystal which is rovided with a flat surface B and a series 0 flat surfaces 0 and D, these surfaces bein on different lanes or angles, so as to make the contour of t e entire crystal appear convex. By this means we provide a series of facets, each of which acts individually as a lens. The lens is adapted to be mounted in the enlar ed open end E of the substantially cone shaped casing F, which is hollow and is provide with the reduced open end or observation or peep hole G. In the enlarged rovide an annular shoulder H, against w 'ch the crystal rests, and in order to hold the same in place we rovide a bead or fastening means J to secure y hold the lens in position.

a series or multiplicity of In the form shown in Figs. 1 and 2 the convex surface of the lens extends outward;

but in the form shown in Fig. 3 the lens is in- 5 5 verted. By this means with the same lens difierent results may be attained, andin order that the lens may be removed we provide the detachable means K, (shown in Fig. 3,) by which means the lens may be removed and inverted at pleasure.

In order to obtain the best results, the en-' tire case or observing-tube is lined with an opague materi aTskTa'sI to" 'r'event an refrac- MTQHQQUOD. within t seine, t us reventing any obstruction to the vlsion w en observing an object through the peep-hole.

From the foregoing description it is evident that we provide a means whereby interesting experiments may be made and also amazing and amusing observations obtained. When looking throu h the peep-hole of either construction as s own in F1 1 or 3, each surface upon the convex s ace of the lens will show its particular object, so that the s' le 7 object at which the device is projected be multiplied according to the number of fafgets and by slightly turning the casing or iiibeithe ob ect appeal FE- rotate, so'that amusing experiments may be obtained.

What we claim as new, and desire to secure by Letters Patent, is

The herein-described device, consisting of a hollow substantially truncated-cone-shaped casing having a small observation-ope and an enlarged lens-receiving opening, sai lens-receiving o ening having a recess or bead, and a lens aving a flat surface and a slightly-convex surface, the convex surface being provided with a plurality of facets, each acting as an individual lens, and means for removably holding the lens within the bead of the enlarged opening of the case; whereby the lens may e removed and reversed at pleasure. 5

In testimony whereof we afiix our signatures in presence of two witnesses.

SAMUEL J. GIBBONEY. JOHN W. RYAN.
